DETAILED DESCRIPTION OF THE INVENTION

[0048] The present invention is further illustrated below in conjunction with the accompanying drawings. As shown in FIG. 1 to FIG. 6, a cutter mesh structure of a rotary shaver includes a cutter mesh body 1. The cutter mesh body 1 is provided with a raised ring shaving track 2. The shaving track 2 includes an outer ring side face 21, an inner ring side face 23, and a track top surface 22 for connecting the outer ring side face 21 and the inner ring side face 23. Outer hair inlet slots 3 and inner hair inlet slots 4 separated from each other are provided in the shaving track 2. The outer hair inlet slots 3 extend from the outer ring side face 21 to the middle of the shaving track 2, preferably, to a position beyond the middle of the shaving track 2. The inner hair inlet slots 4 extend from the inner ring side face 23 to the middle of the shaving track 2, preferably, to a position beyond the middle of the shaving track 2. There are multiple the plurality of outer hair inlet slots 3 and the plurality of inner hair inlet slots 4 which are distributed in a circumferential direction. The outer hair inlet slots 3 and the inner hair inlet slots 4 are in one-to-one correspondence in number, and are staggered with one inner hair inlet slot and one outer hair inlet slot alternating.

[0049] Preferably, the outer hair inlet slots 3 and the inner hair inlet slots 4 are evenly distributed in a circumferential direction of the shaving track 2. Of course, the outer hair inlet slots 3 and the inner hair inlet slots 4 may be distributed by 360° along the entire circumference of the shaving track 2, or the outer hair inlet slots 3 and the inner hair inlet slots 4 may be disposed alternately within a certain range of angle.

[0050] As shown in FIG. 11 to FIG. 13, when a rotating blade 7 is used for cooperation, the rotating blade 7 includes a cutting edge 71 for rotary cutting in the shaving track 2. A rotary cutting area 70 of the cutting edge 71 covers inner termination ends 31 of the outer hair inlet slots 3 on the track top surface 22, and outer termination ends 41 of the inner hair inlet slots 4 on the track top surface 22 at the same time. An outer edge 701 of the rotary cutting area 70 is formed by a rotating trajectory of an outer cutting point of the cutting edge 71. An inner edge 702 of the rotary cutting area 70 is formed by a rotating trajectory of an inner cutting point of the cutting edge 71.

[0051] Of course, in order to improve the cutting effect of the cutting edge 71 for hair at the outer termination ends 41 and the inner termination ends 31, a distance D1 between the outer edge 701 of the rotary cutting area 70 of the cutting edge 71 and the outer termination ends 41 of the inner hair inlet slots 4 on the track top surface 22, and a distance D2 between the inner edge 702 of the rotary cutting area 70 of the cutting edge 71 and the inner termination ends 31 of the outer hair inlet slots 3 on the track top surface 22 satisfy the following relation: 0 < D1 < 0.5 mm, and 0 < D2 < 0.5 mm, preferably, 0.1 mm < D1 < 0.3 mm, and 0.1 mm < D2 < 0.3 mm.

[0052] In the embodiment shown in FIG. 1 to FIG. 6, since the cutter mesh body 1 has the outer hair inlet slots 3 and the inner hair inlet slots 4, and the outer hair inlet slots 3 and the inner hair inlet slots 4 are not through slots penetrating from the outer ring side face to the inner ring side face of the shaving track, hair can enter from the outer ring side face or the inner ring side face of the shaving track, and the hair collection efficiency is high. Since the outer hair inlet slots 3 have the inner termination ends 31 on the track top surface 22, and the inner hair inlet slots 4 have the outer termination ends 41 on the track top surface 22, hair entering the outer hair inlet slots 3 and the inner hair inlet slots 4 can be prevented from running out, and hair blocked at the inner termination ends 31 or the outer termination ends 41 is cut off when the cutting edge 71 rotates to the termination ends, which not only improves the shaving efficiency, but also avoids the hair being pulled and improves the comfort of shaving.

[0053] Since the outer hair inlet slots 3 and the inner hair inlet slots 4 are staggered, while the outer hair inlet slots 3 and the inner hair inlet slots 4 are set to have a safe slot width to avoid skin from being squeezed into the shaving track to be cut, every two adjacent outer hair inlet slots 3 have a wide spacing therebetween, and with the space, outer flared hair guide openings 5 corresponding to the outer hair inlet slots 3 and being used for guiding hair into the outer hair inlet slots 3 are provided in a turning joint between the outer ring side face 21 and the track top surface 22. Although the number of the outer hair inlet slots 3 is decreased, the problem that hair is difficult to collect by an existing cutting mesh structure due to a small width of straight slots is overcome by means of the outer flared hair guide openings 5, and the external hair collection efficiency of the cutter mesh structure is greatly improved.

[0054] In addition, after the shaving track is staggered cutting of the outer hair inlet slots 3 and the inner hair inlet slots 4, a continuous and complete contact surface for contact with skin is reserved on the track top surface of the shaving track. As shown in FIG. 6, the track top surface is staggered cutting by the outer hair inlet slots, the inner hair inlet slots, the outer flared hair guide openings and inner flared hair guide openings, reserving the continuous and complete contact surface on the track top surface for contact with the skin, and the contact surface is defined by S-shaped unit surfaces. Thus, the comfort of shaving is improved, the skin feeling is enhanced, skin squeezing into the shaving track can be prevented, and skin protection is achieved.

[0055] According to the embodiment shown in FIG. 2, the outer hair inlet slots 3 and the inner hair inlet slots 4 are eccentrically disposed in the shaving track 2, so that the different inner hair inlet slots 4 have a large spacing on the inner ring side face 23 to ensure that the inner hair inlet slots 4 have an appropriate width. At the same time, since the outer hair inlet slots 3 and the inner hair inlet slots 4 are eccentrically disposed in the shaving track 2, an angle α is generated between the outer hair inlet slots 3 and a radial direction, and an angle β is generated between the inner hair inlet slots 4 and the radial direction.

[0056] According to the embodiment shown in FIG. 2, since the outer hair inlet slots 3 and the inner hair inlet slots 4 are staggered, while the outer hair inlet slots 3 and the inner hair inlet slots 4 are set to have the safe slot width to avoid the skin from being squeezed into the shaving track to be cut, every two adjacent inner hair inlet slots 4 have a wide spacing therebetween, and with the space, the inner flared hair guide openings 6 corresponding to the inner hair inlet slots 4 and being used for guiding hair into the inner hair inlet slots 4 are provided in a turning joint between the inner ring side face 23 and the track top surface 22. Thus, the hair collection efficiency of the inner hair inlet slots 4 is improved.

[0057] Preferably, the outer flared hair guide openings 5 and the inner flared hair guide openings 6 are respectively V-shaped openings tilting upwards, the outer flared hair guide openings 5 are located on two sides of the outer hair inlet slots 3, and the inner flared hair guide openings 6 are located on two sides of the inner hair inlet slots 4.

[0058] As shown in FIG. 1 to FIG. 6, as an implementation of the outer hair inlet slots 3 and the inner hair inlet slots 4, the outer hair inlet slots 3 and the inner hair inlet slots 4 are straight slots which are simple in structure and convenient to process.

[0059] According to the embodiment shown in FIG. 4, in order to reduce the size, and ensure that the rotary cutting area 70 covers the inner hair inlet slots 4 and the outer hair inlet slots 3 by a certain depth for ensuring good cutting efficiency, each of the inner hair inlet slots 4 extends into a middle area 30 formed between two outer hair inlet slots 3 corresponding to the inner hair inlet slot, so that the outer hair inlet slots 3 and the inner hair inlet slots 4 have overlapping areas in the circumferential direction.

[0060] An upward concave ring shaving groove 25 for rotary movement of the cutting edge 71 of the rotating blade 7 is provided in an inner top surface 24 of the shaving track 2. The outer hair inlet slots 3 extend from outside to inside beyond a center position 250 of the shaving groove 25 and terminate between the center position 250 of the shaving groove 25 and an inner groove wall 251 of the shaving groove 25. The inner hair inlet slots 4 extend from inside to outside beyond the center position 250 of the shaving groove 25 and terminate between the center position 250 of the shaving groove 25 and an outer groove wall 252 of the shaving groove 25.
